This commit enables Kilo to work as an independent networking provider.
This is done by leveraging CNI. Kilo brings the necessary CNI plugins to
operate and takes care of all networking.
Add-on compatibility for Calico, Flannel, etc, will be re-introduced
shortly.
This commit introduces liveness checks to Kilo. This allows the Kilo
daemons to take nodes with inactive or dead Kilo deamons out of the
topology until they are alive again.
